To ali whom t may concern Be it known that I, ALEXANDER- Yum, a citizen of. vthe United States, and a resident ofthe city of St.lLouis and State o Missouri, lhave invented la new and Improvernent in Railway-Crossings, 'of which f the following is a speciicationl.

This invention relates to cross-over struc` l tures-'audit hasfor-its principal objects to in the arrange obviate the poundingjof the-wheels as. they' annoyance to passengersv and 'those residingin the immediate neighborhood of. the crossing, -to lcarry .the v,car .wheel across the 4struc;-

ture withont raising1 or loweri it fromfits normalhorizontal p ane ,.to pro ucc a structure adapted for of various depths, to minimize the. cost o 'in-v stallation -`and upkeep of :cross-over track structures, and to lattainl certainj-other'ad vantages hereinaftermore fully appearing.

` Thein'vention consistslin-the parts and parts liereinaffterdescribed and claimed.

In the acco panying' drawings' which form part of thi like symbols refer they occur-Figure to like lparts wherever l is a toplplan of a rallway crossing embodying myinvention; Fig.

'Z 1s ahorizontalsection on an enlarged scaleon the line 7 -7 o Fig. 2, ,showing the end' portions ofthe flange platesl at one of the points dinger-, 1g.`

section of the cross-over structure; an 8 is a fragmentary 'view showing sai end' portions of the flan e plates detached.'

The crossing illustrated inthe drawingsl comprises an integral casting However, the same may obviously be abnilt-npL structure, if desirable. Each terminal of the crossing comprises a the particular type of the'- adjoining 'rail used in the track proper. i Atthe inner side of the rail is a groove v2,I The deph ofthel groovefQ', at a oi'nt near the ter iinal 'portion l of the rail, is the same f. me depth of the flange of a car wheel. -That is,

the points 3a car wheels having ianges at the point ents i and combinations.- of.

specification and wherein the -inclines 4:,

rail whose tread gp'or'- tion i corresponds to the tread portion of wheel of acertain standard sizeor wheels having-Hangers of the same depth. The bottomlof the groove 2 continues in a Astraight line or horizontalA plane entirely across the crossing excepting portions 3 at the terminals, which are inclined downwardly from nal tread portions 1, as shown moreclearly -at the right of Fig. 2.

From the points 1a some 'distance inwardly towardthe'ends of the termifrom the oints 3a the treads of the rails are,

inclined ownwardly to. the points l, as atv 4, the intermediate portions .5 of the rails `extending between the points of intersection 'of' the rails at lthe lower elevation of the pointslb `on'opposite sides of the points vof intersection.

over thecrossingride's irst with its tread on the terminal v'tread ortion fof the-rail, and 3a, the ange of the wheel passesV tangentially in'graised .zon-tal plane and without a jar or shock. That is,'provided,the depth of the lange of Thus the car'wheel in passing onto the 'bottom ofthe groove 2 before the incline 4 is reached without 'beor lowere d. `outv of its normal horiso i the wheel corresponds to' thedepth' Iof. the Y groovebetween the .points 3a and la. lArs the wheel passes" above the inclined portion 4,

the tread of the'wheel is relieved from the treadof the rail, and the 'wheel travels on its flange across the intersecting points of the. tracks and passes onto the vtread portion l 1j at the oppositeterminal without any perceptiblejar or shock. 1 i Incase the iiange of the wheel is not so deep as the groove, the crossing is still eifective to eliminatey the pounding lconsiderably b y reasonvof the arrangement of travel until its 'flange contacts -with the down whichthe wheel willy Abottom ofthe groove. lO course, .in this instance the wheel is ,necessarily lowered j passing the intersecting'points of the-rails and is raised again as it approaches the jopcase the flange of the wheel 1s deeper than the groove,

lift the -treadof the'wheel froniine tread fromitsno'rmal horizontal plane prior to Y ,10o posite terminal of the crossing. So, too, 1n-

-the -iange will ride; up f'iein'- clinej at the termina-l offthe grooveand los .of the rvailQ` Hence, while the fcrcssing 'isl i designed to' carry the wheel,

[lio

certain standard, yet in case there ,is avariavtion in thedepth of the flanges, the passage guard railsand, adjacent to the. terminalv over the crossing is effected as Vnoiselessly and efficiently as may be accomplished by such crossings that are arranged'for -merely relievin rail by inclined risers to coperate with the flange of the wheel, or by inclining the tread of. the rail downwardly to allow the'flange -of the wheel to contact with the vbottom 'of the. groove, all of which necessitate lower-- ing-and lifting the c'ar from its lnormal Ihorizontal plane and do not entirely eliminate all the shock or jar.

" The portions 6 of the cross-over 'structure' at the inner side of thelgroove constitute portions 1*, correspond substantially to the cross :section ofthe guard flange of an ordinary groove railway rail; but from the points 6 to the points 6b, the incline upwardly, as at 7, to substantially the same. plane as the top of the terminal tread 'portions 1; or, in some cases, to a higher plane, so as to serve as a guard at thel places where -the tread of the rail is cut 'mthefmain or body portion Tof the cross-1 over sti'ucturemay be made square in cross setion'fpand the plates dropped therein and secured by bolts; or, preferably, as shown in .the drawlngs, by formingv undercut grobves or`'chat1nels in the body Portion and dV` ingL Weardplates into them. Preferably, four;` interme iate plates 9 having squared ends a'ld of a length so that their inner corners 91 coincide are first driven into position and 'then the Yterminal plates 10, having miter'ed inner ends 10a so as to meet in the 'crotches formed by the adjacent ends vof the plates 9; are driven into place.. kBy forming the undercut channels and drivingv the plates, the necessity of Ausinga multip lcty of securingfbolt's to hold the plates in position'- is obviated and it is only'necessary to employ abolt 11v at the end inclinedportion 3 of each ofthejterminall plates 10; and the heads of these-bolts being countersunk into' the'incl-inedportions 3, the surface of the horizontal .bottom portion o f the -groove 2 which carries the flange ofthe wheel is unbroken and free from depressionsror projections liableto cause pounding.

Obviously, the structure admits of considerable modification without departing from my'invention. Therefore,` I do not wishto be'limitedto the specific construction 'and-arrangement shown.

the tread of the wheel from the'- ard rails tracks have normal tread faces in the same 7o plane as the tread faces of the adjoining track rails so as Jto-'receive the normaltread. portions Aof car wheels of one landv the. same standard," and; flange-receiving portions ex- "tending across the track-.intersections parallel witlifthe respectivefrails and terminating atpofints' outwardly from the inner i ends of said-normal :tread-'portions thereof,
